H. ROBERTS, O1! E NGLEWOOD. NEW YORK, H. Y., ABSIGNOBS TO FBAN NEW JERSEY, AND FRANK B. PETERS, OI KLIN RAILWAY BUIPLY COMPANY, A. COB! LOCOMOTIVE BOOSTER- Applloatlon flied latch 10, 1928. Serial No. 884,207.

This invention relates to locomotive boost ers and. particularly to the booster motor bed plate construction.

The booster devices to which this invention relates are ordinarily applied to the trailing truck of the locomotive and the service conditions to which they are subjected are most severe and the space available for their applicationis very small.

It is one of the primary objects of our in vention to provide an improved construc tion which is strong and durable, is compact so that it may be applied. is accessible for ins ction an adjustment of the parts, etc.,

an is easy to assemble and take apart; and,

at the same time, being so arranged thatthe necessary machining of the parts, particularly the bed plate proper, can be readily done and the manu acture simplified and cheapened in other ways.

Still another object is to provide a construction of the character described in which the lubrication of the working parts is simple and effective.

95 The foregoing, together with such other objects as may hereinafter appear or are incident to our invention. we obtain b means of a construction which we have i lustrated in preferred form in the accompanying drawings, wherein:

Fig. 1 is a partial plan and sectional view illustrating a booster for a trailer truck embodying our invention; Fig. 2 is a cross section and side elevation of Fig. 1, with certain of the enclosing latcs removed; Fig. 3 is a section taken on t \B'linB 3--3 of Fig. 4; Fig. 4 is a plan view of the booster bed plate roper; Fig. 5 is an end elevation of Fig. 4:

ig. 6 is an end elevation of a combined bearing on and carrying structure forming a detail 0 our improvements; Fig. 7 is a partial section and side elevation of details of our improvements; and Fig. 8 15 a section taken on the line 8-8 of Fig. 7.

Referring now to the drawings, the cylinders 7 and the valve chests 8 of the booster engine are cast en bloc and bolted to the wall 9 rising from the rear portion of the bed ilate, indicated as a whole by the reference letter A. This wall 9 has a ledge 10 at the bottom upon which the cylinder and valve chest casting is supported so as to relieve the attaching bolts of the load.

The bottom or bed plate portion proper,

low 12, suitably generally speakin extends downwardly and for-war ly from t to wall 9 toward the front end, from which end walls 11 and 11 rise, such walls being spaced apart. The rising portions 11 and 11 respectively extend latorally ap roximately to the edges of the bed plate MK projecting forwardly from each of said portions is an inverted bearin pilreinforced by the ri s 13 and ada ted to fit down over the axle 14 of the trai ng truck, one on either side of the gear 15 for driving such axle.

The rear wall 9, the rising portions 11 and 11, and the bearing pillows 12 are cast integral with the bed, and the bearing pillows are tied together by means of a combined tie and hood or shroud member 16, preferably cast integral with the bearing pillows, such member being adapted to shroud the upper portion of the gear 15 on the axle 14. A bearin cap 17 is adapted to be bolted to each of the pillows and the bed plate, as indicated in Fig. 2, such bearing caps, however, being tied together by a tie piece 18 (see Fig. (l) which tie piece also acts as a shroud or hood cooperating with the hood portion 16 to enclose the gear 15 in advance of the portions 11 and 11'. The bearing caps and this combined tying and hood piece 18 are also preferably cast inte al.

T is constitutes a simple arrangement permitting) of read assemblage and tearing down, ut provi in a rigid sup rt; for the axle bearings, whic 1 is of great importance.

The wall portion 9 does not extend out to the lateral side edges of the bed plate but terminates in the region of the inner portions of the cylinders 7, and a rib 19 leads forwardly from each end. of the wall 9 to res ective front rising portions 11 and 11, Sue ribs being formed integral with the bed late and extending in substantial parallelism. Another web 20 extends transversely of the bed plate intermediate its ends, mergbig into the longitudinal ribs .19, and c0- operating therewith to divide the bed plate into four general compartments. two central ones B and C and one on each side, D and E, flanking the central divisions.

The ribs 19 tie the front, and rear rising portions together, stiffen the bed plate and cooperate with the rib 20 to further stiffen the bed plate.
